This study looks at how the experimental drug PF-08049820 is absorbed in healthy adults. It tests three different forms of the drug, taken with or without food, and also with another drug that reduces stomach acid. The goal is to understand the best way to give the drug in future…

This study looks at how eating low or high amounts of fiber changes the compounds in your breath and gut. Twenty healthy adults will try both a low-fiber (10g/day) and a high-fiber (40g/day) diet for three days each, with a three-week break in between. Researchers will measure br…

This study tests whether 5 weeks of breathing endurance training using a special device can reduce breathlessness and improve exercise performance in healthy athletes. Researchers will compare real training to a sham version in 32 cyclists or triathletes. The goal is to understan…

This study looks at how people with mild multiple sclerosis adjust their walking when faced with obstacles or sudden changes, compared to healthy adults. Researchers will use motion sensors and brain activity monitors to measure these skills. The goal is to find better ways to de…

This study watches how healthy adults aged 18 to 65 move their eyes and body when using digital devices while wearing different eyeglasses. Researchers want to see if younger and older (presbyopic) users behave differently. Participants get an eye exam and perform simple screen t…

This study looks at whether eating 2 ounces of pecans daily for 3 months can improve blood fats, inflammation, blood pressure, thinking skills, and gut bacteria in healthy adults aged 45 to 75. Participants will follow two diet periods—one with pecans and one without—and provide …

This early-stage study tests a new drug called MIB-725 in 32 healthy adults aged 19 to 60. Participants receive a single dose (100 to 800 mg) and are monitored for side effects and how the drug moves through the body. The goal is to see if the drug is safe before testing it in pe…

This study in Lahore, Pakistan, is recruiting 60 healthy twins to see how genetics and environment influence the effects of a balanced diet. Over 12 weeks, both identical and fraternal twins will follow a WHO-aligned diet. Researchers will measure changes in body fat, blood sugar…

This study tests which method is more accurate for placing dental implants: a custom-made guide or a dynamic navigation system that shows the dentist where to drill on a screen. Twenty healthy adults with at least one missing upper tooth will take part. The goal is to see which a…

This study tests whether strengthening your breathing muscles with a handheld device and taking nitrate supplements (like those in beetroot juice) can improve exercise performance in simulated high altitude. Eighty healthy adults will train for 4-6 weeks and then do a cycling tes…

This early-stage study is testing a new oral drug called EDG-15400 in 108 healthy adults aged 18 to 59. The main goal is to check if the drug is safe and how well it is tolerated, both after a single dose and after multiple doses. Researchers will also measure how much of the dru…
